PATCH: Changing a control data set record z/OS DFSMShsm Diagnosis GC52-1387-00 |
|
Explanation: PATCH is an optional parameter you specify to change a control data set record. PATCH(offset) allows you to specify a decimal value anywhere from zero up to a number equal to the length of your CDS record, or an equivalent hexadecimal value, for the offset. Hexadecimal characters must be in the form X'n'. The variable data portion of the record is patched starting at the specified offset. PATCH(data) allows you to substitute the changes you want made to the data. You can enter the data as hexadecimal characters or alphameric characters and $, #, or @. You can change up to 256 bytes of data. PATCH(bits), allows you to substitute an eight-character
string specifying which bit or bits you want turned on or off. A period
(.) means do not change bit, a 1 means set bit
on, and a 0 means set bit off. For example,
means set bit 0 off and set bit 2 on and do not change bits 1, 3,
4, 5, 6, and 7.PATCH GEN(nn) allows you to specify the original data set name, along with a generation number, instead of specifying the DFSMShsm-generated name for the backup version data set. When using the GEN(nn) parameter, the FIXCDS required parameter type must be ‘C’. Abbreviations: None. Defaults: If you do not specify one of the optional parameters of FIXCDS, the default is DISPLAY. Note:
